In fact, it turns out Superman actor Henry Cavill is actually a huge Batman fan. So much so that he decorated his entire trailer with Batman merchandise, as you can see in the above clip. It was also really thoughtful of him to sign Cavill's poster. Class personified that Affleck.

At least, that is what Ben Affleck would like you to think. Affleck did such a good job on the trailer makeover, he even took his own Batman mug as a souvenir. I see Affleck's trailer getting a similar Superman themed makeover sometime in the near future.
